Abstract: A method for detecting and measuring a clamping force and/or a braking torque includes encapsulating a fiber-optic strain sensor in a casing and incorporating the casing in a portion of friction material adhering to a base platform of a brake pad, detecting, by the fiber-optic strain sensor, a first strain in a first position of the casing along a first direction and a second strain in a second position of the friction material along a second direction, generating a first photonic signal, representative of the first detected strain, and a second photonic signal, representative of the second detected strain, receiving the first and second photonic signals, by an optical reading/interrogation unit, optically connected to the fiber-optic strain sensor, determining, by the optical reading/interrogation unit, the values of the first and second strains based on the first and second received photonic signals and determining a measurement of the clamping force and/or braking torque based on determined values of the first and second strains.

Abstract: A method for determining a braking torque at at least one fixing interface between a brake caliper body and a brake caliper support includes inserting at least one washer device at the at least one fixing interface, the washer device having at least one fiber-optic strain sensor of fiber Bragg grating type, detecting, by the at least one fiber-optic strain sensor, local deformation and/or strain acting in a respective detecting position, and generating at least one respective photonic signal representative of the detected deformation and/or strain, receiving the at least one first photonic signal, by an optical reading/interrogation unit optically connected to the at least one fiber-optic strain sensor, generating at least one electric signal representative of the detected local deformation and/or strain, based on the received first photonic signal, and determining the braking torque based on the at least one electrical signal.
